Police arrested her ex-husband, Dragan Sekulic, 38, on Wednesday afternoon, charging him with aggravated murder. He was being held on $5 million bond.

At the time of the shooting, Sekulic was out on bond for charges of felonious assault and domestic violence, operating a vehicle while intoxicated and an open container violation. He had rammed his ex-wife's car into a pole near Astoria on Nov. 24, flipping the car upside down.

In a video press conference, Astoria co-owner Michael Slyk, choking up at times, said staff and residents were “heartbroken. We have lost a member of our family.”

There is no indication the murder appears links to the nursing home, but it was immediately locked down following reports of gunfire.

“Our heartfelt condolences go out to the family and those who were affected by this,” he said, describing Sekulic as “well-loved and dedicated.” While he did not cite her length of employment, she “was not a new employee.”

“Today it's hard to find great staff. We lost someone very special today. It's a tragedy and is a loss for everybody here, including all of our guests,” Slyk said.

Fecal transplants should be considered for patients with recurrent cases of Clostridium difficile whose symptoms cannot be addressed by antibiotics, the Infectious Diseases Society of America said in new guidelines published Thursday.

Lawmakers took a long-standing industry complaint to the Department of Health and Human Services this week, telling Secretary Alex Azar that Medicare and Medicaid favor opioid prescription over non-addictive alternatives for treating chronic pain.
